Re: [BKARTS] Traditional bookbinding [inkjet]

This is in response to the question about using an inkjet printer to print
on rigid materials like wood and metal. The information below is from the
introduction to:
Digital Art Studio: Techniques for combining inkjet printing with
traditional art materials
by Karin Schminke, Dorothy Simpson Krause, Bonny Pierce Lhotka
Watson-Guptill (Summer 2004 release)

1. Precoats: To maximize the quality of the ink printed on inkjet printer
papers, canvases, films, and other media, manufacturers "precoat" their
surfaces with proprietary products. The most predictable matches between
printer, ink, and media (and often the most expensive) are those provided by
the printer manufacturer itself. The receptor coating on inkjet media is
carefully designed to control the size of the inkjet dot, to adhere the
water-based ink to the substrate, and to speed drying time. The back coating
on ink jet media helps keep the substrate flat and dimensionally stable as
it moves through the printer.

Three kinds of commercially applied precoats are gel, microporous, and white
matte. Gel type precoats, originally made from gelatin, are now made from
swellable co-polymer. This precoat feels sticky when pressed with a wet
finger and acts like a monoprint release medium ,allowing any image printed
onto it to be transferred to another surface. Because manufacturers want to
keep the precoat and your printed image from moving, they add an adhesive
layer to destroy the precoat's transferability. Microporous precoats are
often advertised as ³universal.² They work with most inksets, dry
immediately, exhibit no dot-gain, and cannot be used for transfer processes.
White matte precoats, usually used on paper or canvas, contain precipitated
calcium carbonate and are water resistant.

There are very few do-it-yourself coating products that you can use to
prepare unusual substrates for inkjet printing. One is a gel type homemade
precoat, rabbit skin glue, which artists have used as an adhesive and binder
for centuries. Before the advent of acrylics, it was used to prepare or
³size² canvas and fabric for painting, and was a major component in
traditional gesso. You can purchase rabbit skin glue from many manufacturers
in various forms (from sheets to powders) and in various degrees of purity.
Each source has its own recipe for preparation. For consistency and
availability, the processes in this book have been made using Daniel Smith
Rabbit Skin Glue granules.

inkAID? sells three precoat products that you can apply to your substrates.
inkAID Clear Gloss and Clear Semi-Gloss are gel type precoats which allow
the color of the substrate (and any image printed beneath the precoat) to
show through. Because inkAID precoats are clear, they are used for most of
the processes in this book. inkAID White Matte precoat is calcium
carbonate-based. It goes on clear but dries to a very flat and bright white
surface that is water-resistant when printed with pigmented inks

Testing precoats on your substrates before using them for making art is
always a good idea.
